Week 8 Worm Gear Challenge

AIM:

Perform a transient structural analysis on a worm gear assembly and find Equivalent stress, Equivalent elastic strain and the total deformation.

PROCEDURE:

1. Download the model from the challenge.
2. Open the ANSYS workbench and drag the transient structure analysis.

3. Double click on the engineering materials and add if any material we want to add.
4. now right click on the geometry, import the model downloaded.
5. Now double click on the model. And check the model loaded properly or not.

6. Now click on the geometry in the outline tree. And name the material according our convience.
7. Now click on the contacts. It shows some default contacts. And make that re arrange the contact on basis of definition. and chnage the type from rigid to friction less.

8.Now insert two to body to ground revolte joint as shown below.

9. Click on the mesh, Now generate the mesh.

10. Now go to analysis setting, set the 15 steps to run the solution.

11.make it ON Large deformation. and also change the setting as shown below.

12. Now insert the joint rotation with each 50 deg angle different in each step.

13. Now insert the solution parameters as shown below.

14. Now solve the model. during the solving the proble we can see the force convergence.

15.After providing the solution it shows the following results.

CONCLUSION :

After completing of this analysis, i got follwing results stress is 1301.7 MPa, total deformation is 7.2652 mm and strain is 0.007185.

(NOTE: I was tried to cut half section of gear but number of elements which i got under acceptable range of student edition. so, i continued with full model.)
